"Why won't he just talk"
Everyone asks him that question. He can hear people whispering around him. He hates school more than anything. He is the only one that knows the answer. He can't. The sound can't come out of his mouth. No matter how hard he tries. It seems like a knife is stabbing his in his vocal chord.
Brodie Sarmans cannot speak and no one knows why. he doesn't know why either. He is a nobody that people occasionally make fun of. Just the average predator to mean strong kids. He had never said a word in his life until one day he spoke.
